SPLINT.

SPECIFICATION forming part of Letters Patent No. 282,650, dated August'7, 1883.

Application filed June 9, 1883. (No model.)

I To aZZ whom, it may concern Be it known that I, ROBERT LE BARON, ofPontiac, in the county of Oakland and State of Michigan, have inventednew and useful Improvements in Splints; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing, which forms a part of thisspecification.

This invention relates to certain new and 'useful improvements in springindicating counter extension splints; and the invention consists in thepeculiar construction, arrangement, and combination of the variousparts, all as more fully hereinafter set forth, and pointed out in theclaim.

In the accompanying drawing myimproved splint is shown in perspective,in which A represents the splint, which is formed from any suitablematerial. In the lower end of this splint is formed a slot,. a, in whichthe crosshead B slides, so as to adapt the splint to a longer or shorterlimb, such crosshead being secured to its adjusted position within theslot by means of the pinb, which passes through one of the series ofholes in the splint and through the center of the cross-head. Both armsof this cross-head are slotted longitudinally, as shown, and in each ofthese slots is adjustably secured a groove-pulley, O, in such mannerthat the pulleys may be adjusted to or from the splint by means of thepins 7).

Upon the outer face of the splint, and near the top end thereof, issecured a suitable hook,

which engages With the eye upon the end of the graduated spring-balanceD, while the spring-arm of such balance is secured to one end of a ropeor cord, E, the opposite end of which passes over the groove-pulleys inthe cross-head, and is secured to the fractured limb by means ofadhesive plaster, as employed in the ordinary method of applyingextension.

After the fractured limb has been prepared for the reception of thesplint, the splint is secured to the limb by a roll or bandage, as inthe ordinary manner of adjusting the long splint, the cross-head beingadjusted at some little distance from the foot. The free end of the cordis now secured to the fractured limb in the ordinary manner, and in sucha way that the graduated balance will exert a con tinual pull upon thecord, creating what may be called an extension of the fractured limb,the counter-extension of which is the bandage or roll about the thigh.

By the employment of a splint constructed as above described it canreadily be seen that the patient can be moved easily without disturbingor in any way hindering the operation of the device, and the spring willexert its extending force upon the fractured limb no matter in whatposition it may be placed.

1 am aware of Patents Nos. 76, 382 and 82, 47 8, and make no claim tothe construction shown therein.

What I do claim as new is The within-described splint, consisting of thebody A, having longitudinal slot a,with side holes, the cross-head B,held in an adjusted position in said slot by a pin, 12, and havingpulleys C j ournaled in each arm of said crosshead, one upon either sideof the splint-body, the spring-balance D, secured to one face of thesplint-body, and the rope E, leading from said balance over the pulleys0, its free end being adapted to be secured to the fractured limb or thebandages thereon, all combined and ar-- ranged for joint operation, asand for the purposes set forth.
